Door knobs/handles and locks

[Dani U.]

Hello! I have 2 questions:

1.) I have door knobs throughout the house, would putting door levers on the master bedroom's double doors look odd? It would the same brushed satin nickel finish. I think the door levers would look better for double doors but the rest of the house has knobs.

2.) Is it recommended to have no locks for the bedroom doors or are privacy locks ok? (Not keyed locks)

Thank you for your help!
